Biofield Theory， as an emerging field of quantum philosophy， aims to unveil the mystery of life by describing a holistic electromagnetic field rich in energy and information. With the development of quantum mechanics and electromagnetic theory， Biofield Theory takes a systematic approach and advocates for downward causality in complex mental systems， providing a brand?new perspective for the comprehensive research of spiritualism and physicalism. Under the paradigm of system theory， the “multi?world interpretation” reconstructs the systemic view of biofield and characterizes the causality of quantum’ covert teleportation processes. On the basis of complying with traditional physical laws， Biofield Theory has opened up a new path for quantum philosophy research and has important inspiration for the study of systemic biology philosophy and scientific epistemology.
